A collection of fifty one landraces of rice from gangetic
alluvial zone was taken for the evaluation and characterization based on twenty
eight essential qualitative traits. Distinctiveness, Uniformity and Stability
test (DUS) was done during the kharif season at the research farm of Sripat
Singh College, Jiaganj, Murshidabad and at the Zonal Adaptive Research Station,
Krishnagar, Nadia, West Bengal. Each cultivar was found distinct in respect to
the variability found among the twenty two essential and twenty four additional
traits. There was a remarkable variability in respect to anthocyanin coloration
in different body parts like seed apicular part, collar, auricle, basal leaf
sheath, leaf, seed coat of maximum cultivars. Conservation of these cultivars
is now keenly essential for future rice breeding work. These cultivars may
serve as a superior germplasm in the coming environmental biotic and abiotic
hazards. DUS test is very important tool based on morphological parameters and
geographical influence reflecting the genetically background for the particular
traits. Mode of exploration of rice cultivars through DUS test would obviously
help the rice researchers and scholars to make a promising ground to feed the
quality food to the mass saving from hunger.
